Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在版本 1.4.9 之前的 openssl_encrypt 中存在一个签名验证漏洞： 函数仅检查 状态，而未检查 、 或 GPG 的退出码，导致其接受了已被吊销和已过期的密钥。攻击者若持有曾被吊销的签名密钥或已过期的项目密钥，便可绕过签名验证，从而在宿主进程中执行恶意插件。

Vulnerability Title
openssl_encrypt before 1.4.9 GPG Signature Verification Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
openssl_encrypt versions before 1.4.9 contain a signature verification vulnerability in gpg_runner.verify_detached that accepts revoked and expired keys by only checking VALIDSIG status without inspecting REVKEYSIG, EXPKEYSIG, or gpg exit codes. Attackers holding compromised-then-revoked signing keys or expired project keys can bypass signature verification to execute malicious plugins in the host process.
